the universal relay SKR
The strengths of the SKR industry
relay lie in the mature and thought-
out construction.
Over-average contact safety and life
time, electrical and mechanical sta-
tus indication as well as the unsur-
passed construction from only six
assemblies makes the relay to the
excellent power switch.
8 adjustable functions and 8 selec-
table time ranges: these are the
special features of the time module
STM. With only one version of the
module all essential features as
operating voltage, functions and
time ranges are adjustable.
The result: a simple and cost-effec-
tive warehousing.
Simple to handle screw-terminal
and clear, rich in contrast labeled
clamp identification, are the base
for a problemles use.
The ZKE/ZKX sockets permit a rapid
and secure installation.
The separated inputs and outputs
are located at one level. There is
also the possibility to plug a time
module STM or other additional
modules together with the SKR
relay.
